You’ve got to love Instagram, not because it’s some innovative mobile app worth billions of dollars, but because it makes everyone look pretty good and encourages people to take more pictures of themselves and that means even more celebrity self shots for me. Here’sAshley Tisdale having a rough time lounging in her bikini in a waterfall. Yes! I know the chick is just a reality TV star or a singer, I still don’t really know what the hell it is that she does, but she looks really good in a bikini. Nice job.
